[SGD02-P14] Proposal to avoid inserting leap seconds
Keywords:leap scond, avoid leap seconds, global warming
In the following ** mearns 'power
O means omega
P: pi
Introduction
The leap seconds are introuced to fill the diffrence between UTC and UT1, and have been inserted 27 times during past 45 years.
Decrease of Earth rotation rate
T ; rotation period,
O ; angular speed,
i; means equal,
P; means pi.
Present definition of one second is that 9192631770 times multiply of one period of Cs radiation f = 9.192631770 GHz. As 27 times leap seconds are inserted during 45 years, the leap seconds become unnecessary where the time is made longer by 27 seconds during 45 years. Namely f is made to be fc = 9.192631673. Because
T = 2 P/O
dT/dt = 27 sec / 45 year
= 19.01 * 10**-8
f * dT/dt = 97 Hz
9192631770 / 9192631673 = 1 + 1.055 * 10**-8
This means one second becomes longer by 1.055 * 10**-8 sec
The definiton of light speed c changes, as the definition of time changed, the value is unchanged because the speed and time duration are offset.
Calculation showes that present half life of the anular speed becomes shorter than that of the ancient one. This will be caused by the increse of the moment inersia of the earth which is caused by the global warming.
Although astronomical observation has shown the decrease of the earth rotation rate, this paper shows the rate has become larger, and the reason is the global warming. And the change of the definition of time makes the insertion of leap seconds unnecessary (Refer to attached figure).
